       4. A press apparatus according to claim 1, wherein said means for effecting the parallel feeding includes at least three independently driving lift means, said lift means driving together with one another during the press. 
     
     
       5. A press apparatus for planar members having: means for conveying a first planar member;   means for stopping and positioning said first planar member at the terminal end of the conveyance;   a chuck;   means for shifting said first planar member to said chuck;   means for displacing said first planar member to a predetermined position on said chuck;   a first transfer table for transferring said chuck to a press position;   a second transfer table for transferring a second planar member to the press position;   means for aligning said first and second planar members;   means for effecting the parallel feeding of said first and second planar members; and   means for pressing said first and second planar members with a predetermined pressure.   
     
     
       6. A press apparatus according to claim 5, wherein said first and second transfer tables are rotatively moved to the press position substantially at a time. 
     
     
       7. A press apparatus according to claim 5, wherein said conveying means is displaced in a direction orthogonal to the direction of conveyance when said first planar member is shifted to the chuck. 
     
     
       8. A press apparatus according to claim 5, further having: means for returning the pressed first and second planar members to said first transfer table;   means for transferring said first transfer table in the opposite direction and returning the pressed first and second planar members to the conveying means; and   means for displacing said means for stopping and positioning so as not to be an obstacle to conveyance.   
     
     
       9. A press apparatus according to claim 8, wherein said means for conveying the first planar member has a guide for regulating the direction orthogonal to the direction of conveyance, and said guide is displaced so as not to be an obstacle to conveyance when the pressed first and second planar members are conveyed. 
     
     
       10. A press apparatus for planar members having: a first chuck for holding a first planar member;   a first transfer table for transferring said first chuck to a press position;   means for inclining said first chuck in accordance with the inclination of the upper surface of said first planar member;   a second transfer table for transferring a second planar member to a press position;   a second chuck for adsorbing the upper surface of said second planar member;   means for inclining said second chuck in accordance with the inclination of the lower surface of said second planar member;   means for aligning said first and second planar members; and   means for pressing said first and second planar members with a predetermined pressure.   
     
     
       11. A press apparatus according to claim 10, wherein said first and second transfer tables are rotatively moved to the press position substantially at a time. 
     
     
       12. A press apparatus according to claim 11, wherein said first and second transfer tables are rotatively moved by a Geneva mechanism. 
     
     
       13. A press apparatus according to claim 11, wherein said first and second transfer tables are rotated in opposite directions. 
     
     
       14. A press apparatus according to claim 10, wherein said means for inclining the first chuck is provided with at least three independently driving lift means, said lift means driving together with one another during the press. 
     
     
       15. A method for pressing a planar member comprising the following steps: (a) providing a press apparatus;   (b) rotatively transferring a first planar member to a press position of said apparatus employing a first transfer table;   (c) rotatively transferring a second planar member to said press position of said apparatus employing a second transfer table substantially simultaneously with the transfer of said first planar member to the press position;   (d) aligning said first and second planar members;   (e) effecting parallel feeding of said first and second planar members; and   (f) pressing said first and second planar members with a predetermined pressure employing said apparatus, wherein said planar members are rotatively transferred to the press position by rotatively moving said first and second transfer tables to the press position.   
     
     
       16. A method according to claim 15, wherein said rotational transfers of the first and second planar members are directionally opposite to each other.
